Optimal Topology Transition

no code implementations22 Aug 2022 Tong Han, David J. Hill, Yue Song

This aims to find the topology transition trajectory from an initial topology to a desired terminal topology, which optimizes certain transition performance and satisfies operational constraints.

Formulating Connectedness in Security-Constrained Optimal Transmission Switching Problems

no code implementations6 Feb 2022 Tong Han, David J. Hill, Yue Song

This paper focuses on the issue of network connectedness (NC) in security-constrained optimal transmission switching problems, which is complicated by branch contingencies and corrective line switching.

Dispatch of Virtual Inertia and Damping: Numerical Method with SDP and ADMM

no code implementations25 Jul 2021 Tong Han, David J. Hill

Virtual inertia and damping provided by inverters are essential to synchronism and frequency stability of future power grids.
